Return loss for low input impedance (1Hz to 40MHz)
> 25dB (VSWR < 1.12)
Noise floor for the gain measurement Conditions:
Resolution bandwidth = 10Hz, select internal reference,
PSOURCE = 13dBm, 50O load at CH2, 20dB attenuators for
CH1 and CH2
1Hz to 5kHz: -100dB (typical)
5kHz to 50kHz: -110dB (typical)
50kHz to 20MHz: -115dB (typical)
20MHz to 40MHz: -110dB (typical)
